.SH DESCRIPTION
.sp
.LP
These functions compute the complex arc hyperbolic sine of \fIz\fR, with branch
cuts outside the interval [ -\fIi\fR, +\fIi\fR] along the imaginary axis.
.SH RETURN VALUES

.LP
These functions return the complex arc hyperbolic sine value, in the range of a
strip mathematically unbounded along the real axis and in the interval [
\(mi\fIi\fR\c
